I learned on CNN yesterday that after the latest bit of fundraising Pinterest is valued at 5 billion, up 32% from 7 months ago, when it was valued at 3.8 billion.
Today I read some newspapers articles to see what it's all about. Judging from the facts (no revenue yet, just 750 million users and 30 billion pins), it may very well be a bubble, as many people comment. At the same time, given how many people look for recipes, travel photos and info, and wedding and fashion ideas there, their new promoted pins are likely to be a winner, given that, as Pinterest cofounder and CEO Ben Silbermann says, people come to Pinterest to discover things (whereas they go to Google to research specific things: take, for instance, looking for Mother's Day gifts versus searching for sterling silver jewelry with her favorite gemstone). Also, as its proponents say and as the news anchor on CNN remarked as well, many people come on Pinterest with the intention to buy.
There is also the issue of consumer data as big data, which, as some analysts say, is even more valuable than the clicks leading to the sale of one product or another, even as the returns on some of these clicks may be quite big: consider airline tickets or travel packages, wedding gowns, etc.
